Lines Line Segments Rays Planes Video Lessons Diagrams Examples A ray extends indefinitely in one direction, but ends at a single point in the other direction. that point is called the end point of the ray. note that a line segment has two end points, a ray one, and a line none. an angle can be formed when two rays meet at a common point. the rays are the sides of the angle. Introduction. a point and a line are considered as one of the most fundamental building blocks of geometry. a line segment, a ray and a plane are the geometrical objects which can not be drawn without the help of a point and line. this chapter discusses the definitions and examples of point, line, ray, line segment and a plane.
Point Lines Line Segments And Rays Example With Symbol A ray starts from a point and goes to infinity. a line has no end points. a line segment has two endpoints. a line segment connects both endpoints. if the two lines cannot meet at any point, they are called parallel lines. three or more points on the same line are said to be collinear points. Postulate 1: a straight line segment can be drawn joining any two points. postulate 2: any straight line segment can be extended indefinitely in a straight line. before we go further, we will define some of the symbols used in geometry in figure 10.3: figure 10.3 basic geometric symbols for points and lines.

A ray has two points joined by a straight line segment. but at one point the line extends indefinitely and at the other point it does not. hence, rays extend only in one direction. when naming a ray, it is shown by putting a little ray symbol on the top of the two points and the arrow depicts the direction in which the ray extends. for example:.
